1. Performance feature
Feature: The great advantages are simple control on producing techniques, better working atmosphere, stable pipe quality, adjustable pipe length, easier to change specifications, more convenient operation, etc.
This winding machine adopts the whole closed-loop computer control system, which is developed with Tsinghua University. Designed with the internal and external control mode, it has the characters of accurate control, random selection, stable and easy operation. In the external control mode, all the control for the winding operation can be accomplished simply on the winding car, which can save the manpower.

There are many ways to add sand and they are optional according to the users' requirement. The max thickness of the sand can be added is 20mm in one time. Just by inputting the thickness of sand and resin ration into the computer interface, then the quantity of the sand and glue will be precisely calculated by the computer with an accuracy of ± 2%, which represents the most advanced domestic technology currently. The quantity of resin in the sand layer is accurately controlled by the computer, this can save the cost and improve market competitiveness greatly. The sand adding equipment is set up with synchronous and automatic roll extrusion device, so the sand layer can be made more level and tight, wthich will improve the external and internal quality of products and effectively reduce the pipe cost.

Basic allocation of production line
Liner making machine: It is set up with Taida PLC numerical control device. The winding film, mat and gridding fabric can be controlled automatically by the tension bracket device which makes the lap joint is smooth and precise, so the artificial nonuniformity and waste phenomenon will be prevented.
Winding machine: The sand-adding method includes many modes: Intermediate, bottom, dry, wet and dry-wet method. By being set up with automatic glue-supplying pumping station and mixer, ratio of sand inclusion is fully automatic and well-distributed, so the operation of the equipment is pretty convenient and accurately, low energy-consuming.

Curinging station: It includes open style and closed style. It's allocated with infrared heating system and the mould revolves automatically.
Demoulding machine: It adopts hydraulic transmission and the movement is stable. The flexible distance of claw is long and the applying scope of diameter is wide. It saves the usage of mould-extracing loop so the operation is easier.
Double-duty machine of mandrel: with the collocation of highly-accuracy lathe bed, splint and splint-driven system, it can trim the pipes and also manufacture the moulds, by this way, the double-duty utilization is realized, which can save a lot of investment on mould for customers.
